Democratic Arizona Gov. Katie Hobbs chooses former Republican Mayor John Giles as her running mate

Democratic Arizona Governor Katie Hobbs selected Republican-turned-independent John Giles as her lieutenant governor running mate on August 10, 2026. This marks a significant shift in Arizona's political landscape, as the state has traditionally been a Republican stronghold. Giles, who served as Mesa, Arizona's mayor from 2014 to 2025, is now poised to become the state's first lieutenant governor.

This choice by Hobbs signals her intention to appeal to Republicans and conservative independents in an effort to secure a victory in the upcoming gubernatorial election. It also highlights the significant Republican registration advantage that has emerged in Arizona since Hobbs narrowly defeated Kari Lake, a prominent ally of former President Donald Trump, in 2022.

As the most vulnerable Democratic governor in the country, Hobbs faces a tough reelection campaign. Giles, who declared his party affiliation as independent on May 17 and voted in the Democratic primary, is seen as a moderate who still identifies as conservative. He previously criticized Trump's policies and even endorsed Kamala Harris, the Democratic nominee for vice president in 2024.

During his tenure as Mesa's mayor, Giles advocated for equal treatment of LGBTQ+ residents and supported Democratic candidates running against Trump loyalists. The Biggs campaign, the Republican nominee for governor, has already begun to counter Hobbs' choice by emphasizing Giles' support for Harris during the 2024 election and his participation in the Democratic National Convention.
